The problems were found out from its application at home and abroad. The aim was to provide the reference that developing and revising the assessment tools of nurses′humanistic that fit for the Chinese local culture.

Objective To investigate the expression of interleukin 6 (IL-6) in tumor microenvironment of natural killer/T cell lymphoma (NKTCL) and its relationship with clinical characteristics and prognosis. Methods From January 2005 to December 2012, 93 patients with NKTCL and available paraffin-embedded tissue in Sun Yat-sen University Cancer Center were included. The expression or IL-6 in tumor microenvironment was investigated by immunohistochemistry. The positive IL-6 expression was identified as≥10 cells/HP. The enumeration data and measurement data were compared by t test andχ2 test, respectively. Overall survival (OS) and progression free survival (PFS) were estimated with the Kaplan-Meier method. Survival rates were compared by the Log-rank test. Statistical significance was determined at a level of P<0.05. Results The median count of IL-6 positive cell number was 21 cells/HPF (range, 0-150 cells/HP), and 61.29%(57/93) patients were positive. Positive IL-6 expression was mostly associated with fever and high Korean prognostic index (KPI) score (both P< 0.05). The serum c-reactive protein (CRP) level was (29.28 ± 2.62) mg/L in IL-6 positive patients and (11.14±2.77) mg/L in IL-6 negative patients (t= -2.276, P= 0.025). Patients with negative IL-6 expression had better survival, with 52.7 % of 5-year PFS rate,and 60.0 % of 5-year OS rate; the 5-year PFS and OS rates in those with IL-6 positive were 23.6 % and 27.1 %, respectively (both P= 0.001). Conclusion The high expression of IL-6 in patients with NKTCL might be associated with adverse clinical feature and poor survival.

AIM:To observe the changes of tear film on the patients after laser in situ keratomileusis ( LASIK) with corneal flap created by femtosecond laser with Oculus corneal topography.
METHODS:Totally 120 myopic patients (240 eyes) were collected who underwent femtosecond laser surgery LASIK from August to September 2013, and these patients can be followed up for 3mo. Tear break-up time ( BUT) and tear meniscus height ( TMH ) with Oculus corneal topography were recorded preoperatively and postoperatively at 1wk;1, 2 and 3mo.
RESULTS: Oculus BUT: there existed obvious differences (P=0. 012, 0. 000, 0. 023<0. 05) in 1wk, 1 and 2mo compared with the preoperative level. While no such obvious difference ( P = 0. 236 > 0. 05 ) existed in 3mo compared with the preoperative level. TMH:there existed obvious differences (P=0. 025, 0. 019, 0. 026<0. 05) in 1wk, 1 and 2mo compared with the preoperative level. No such obvious difference ( P = 0. 375>0. 05 ) existed in 3mo compared with the preoperative level.
CONCLUSION: Femtosecond laser surgery affects the stability of the tear film at a certain time and a certain extent. The mechanism related to many factors. It is temporary and lighted.

AIM: To observe the changes of tear film on the patients after laser in situ keratomileusis ( LASIK ) with corneal flap created by femtosecond laser with the different gender.
METHODS: The 120 myopic patients ( 240 eyes ) who underwent femtosecond laser surgery LASIK from August to September 2013 were collected, and these patients were followed up for 3mo. The patients were divided into two groups according to the gender, group A was male (110 eyes of 55 patients); group B was female (130 eyes of 65 patients). Dry eye symptom score, tear break-up time ( BUT ) , Schirmer Ⅰ test, corneal fluorescein staining were recorded preoperatively and postoperatively in 1wk,1,2,3mo.
RESULTS: Dry eye symptom score: it was statistically significant between two groups after operation in the 1wk, 1, 2mo(P = 0. 000,0. 023, 0. 030). It had no statistical significance between the two groups in 3mo(P=0. 283). BUT: it was statistical significance between two groups after operation in the 1wk, 1, 2, 3mo ( P= 0. 000, 0. 017, 0.026, 0. 032 ). Schirmer Ⅰ test: it was statistically significant between two groups after operation in the 1wk, 1, 2mo(P = 0. 012,0. 024, 0. 018). It had no statistical significance between the two groups in 3mo ( P=0. 206 ) Corneal fluorescein staining:it was statistically significant between two groups after operation in the 1wk, 1, 2, 3mo (P=0. 022,0. 015, 0. 036, 0.041).
CONCLUSION: The influence of tear film after femtosecond laser surgery for men less than that for women.

To observe the changes of tear film on the patients after laser in situ keratomileusis(LASlK)with corneal flap created by femtosecond laser and microkeratome.
●METHODS: Totally 150 patients (300 eyes) with myopia received operation of LASlK. Patients were divided into two groups according to the methods of making corneal flap. The patients of group one were assigned to receiving LASlK with corneal flap creation by lntralase femtosecond laser (190 eyes of 95 patients), group two were assigned to receiving LASlK with corneal flap creation by microkeratome ( 110 eyes of 55 patients ). Dry eye symptom score, tear break-up time (BUT), Schirmer Ⅰtest(Slt), corneal fluorescein staining(FL)were recorded preoperatively and postoperatively at 1wk; 1, 3 and 6mo.
●RESULTS: Dry eye symptom score: there existed obvious differences at 1wk; 1, 3mo between two groups(P<0. 05). While no such obvious differences existed in the 6mo between two groups(P>0. 05). BUT: there existed obvious differences at 1wk, 1, 3mo between two groups(P<0. 05). While no such obvious differences existed at 6mo between two groups(P>0. 05). SchirmerⅠ test: there existed obvious differences in the 1wk, 1, 3mo between two groups(P<0. 05). Whileno such obvious differences existed in the 6mo between 2 groups(P>0. 05). FL: there existed obvious differences in the 1wk, 1, 3mo between two groups(P<0. 05). While no such obvious differences existed in the 6mo between two groups(P>0. 05).

OBJECTIVETo observe the intervention effects of electroacupuncture at "Yishu" (EX-B 3) on rats with type-2 diabetes mellitus (T2DM), so as to provide experiment references for acupuncture to treat T2DM.

METHODSAmong seventy male Wistar clean-grade rats, 8 rats were randomly selected into a control group; the rest rats were made T2DM model. Fifty-two rats which were successfully made T2DM model, according to randomized block method, were divided into a model group (10 rats), a medication group (10 rats), an electroacupuncture at "Shenshu" (BL 23) group (11 rats), an electroacupuncture at "Pishu" (BL 20) group (10 rats) and an electroacupuncture at "Yishu" (EX-B 3) group (11 rats). Seven days after successful establishment of model, the rats in the model group were fixed in the self-made rat bag without receiving any treatment; the rats in the medication group, according to body mass (10 mL/kg), were treated with intragastric administration of glimepiride; the rats in all the electroacupuncture groups were treated with electroacupuncture at "Shenshu" (BL 23), "Pishu" (BL 20) and "Yishu" (EX-B 3), respectively. The continuous wave was selected with a frequency of 15 Hz and a current intensity of 4 to 6 mA. The treatment was given 20 min per treatment, once a day, 5 treatments per week for continuous 4 weeks. Before the establishment of model and continuous 4 weeks after the intervention, blood samples were collected from rats' caudal vein, and fasting blood glucose (FBG) was measured with FBG device each week. After the last intervention, the rats were killed and hypothalamus, pituitary and adrenal gland were collected. The colorimetric method was applied to measure the contents of triglyceride (TG), cholesterol (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C); radioimmunoassay was used to test the contents of glycated serum protein (GSP), fasting insulin (FINS), corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH) and cortin (CORT).

RESULTSFour weeks after the intervention, except that the rat's body mass in the normal group continued to increase, body mass in the model group, medication group and each electroacupuncture group were significantly reduced (P<0.01, P<0.05). Compared with the model group, the FBG in the electroacupuncture at "Pishu" (BL 20) group and electroacupuncture at "Yishu" (EX-B 3) group were obviously reduced (P<0.05, P<0.01); FBG in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (both P<0.05). The contents of TG, HDL-C and LDL-C in the electroacupuncture at "Yishu" (EX-B 3) group were reduced (P<0.05, P<0.01), the content of TG was significantly lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (both P<0.05), the content of LDL-C was significantly lower than that in electroacupuncture at "Shenshu" (BL 23) group (P<0.05). Insulin sensitivity index (ISI) in the medication group, electroacupuncture at "Pishu" (BL 20) group and electroacupuncture at "Yishu (EX-B 3)" group were evidently increased (P<0.05, P<0.01); ISI in the medication group was lower than that in the electroacupuncture at "Yishu" (EX-B 3) group (P<0.05). The content of CRH in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Shenshu" (BL 23) group (P<0.05, P<0.01); the content of CORT in the electroacupuncture at "Yishu" (EX-B 3) group was lower than that in the medication group and electroacupuncture at "Pishu" (BL 20) group (both P<0.05).

CONCLUSIONElectroacupuncture at "Yishu" (EX-B 3) could reduce the level of CORT to improve the insulin resistance in rats with T2DM, improve insulin sensitivity index, regulate blood lipid metabolism and relieve the hyperactivity of the HPA axis.

AIM: To evaluate the safety, efficacy and stability of posterior chamber phakic intraocular lens ( ICL ) implanation and clear lens extraction for the correction of high myopia.
METHODS: The study enrolled 56 cases ( 100 eyes ) of high myopia. Group I comprised 32 cases ( 58 eyes ) receiving ICL implantation and Group II comprised 24 cases (42 eyes) undergoing clear lens extraction. In this study, we evaluated the two groups of subject's the visual and refractive results, intraocular pressure ( IOP ) , endothelial cell density ( ECD ) , anterior chamber depth ( ACD) , lens transparency, the surgical complications as well as visual adverse symptoms before and after surgery.
RESULTS: The postoperative subjects in group I and group II were followed, uncorrected vision acuity ( UCVA)>0. 5 were 69. 0% in group I and 71. 4% in group II after 3mo. UCVA>0. 5 were 72. 4% in group I and 73. 8% in group II after 1a. Predictability of the manifest spherical equivalent refraction within±1. 00D was achieved in 62. 1%of eyes in group I and 57. 1% in group II after 1a. The central vault of the ICL ( distance from posterior surface of ICL to the crystalline lens ) measured with anterior segment optical coherence tomography ( AS-OCT ) was 0. 35-0. 54 (0. 40±0. 16) mm. Twelve point one percent of eyes in group I and 7. 1% of eyes in group II had transient mild increase in IOP. Here were statistically significant differences between preoperative and postoperative ECD (P<0. 001 ). Complications of surgery: 1 eye had ICL spontaneous rotation, 2 eyes had anterior subcapsular cataract, 4 eyes noticed halos around lights at night in group I. Three eyes had posterior capsule mild opacification, 3 eyes noticed halos around lights at night, 12 eyes had difficulty in near vision in group II.
CONCLUSION: ICL implantation and clear lens extraction are effective, safe and predictable surgical option for the management of high myopia. No severe complications occurred, but its long time effect and safety still need more time to prove.

Objective To investigate the clinical value of automated breast volume scanner(ABVS) system in detection musculoskeletal system lesions.Methods Totally 49 patients were scanned by Acuson S2000 ABVS system after conventional ultrasound examination.The scanning data of ABVS were stored and automatically reconstructed to obtain coronal and sagittal images.Then the results were analyzed and the occurrence rates of circle sign of different lesions were compared.Results The images of 49 lesions were obtained with ABVS and conventional ultrasound successfully.Statistical difference of the occurrence rate of circle sign was found between benign and malignant lesions (x2 =5.559,P =0.021).However,there was no statistical difference between hemangioma and malignant lesions (x2 =2.098,P =0.156).Meanwhile,a missed lesion in conventional ultrasound examination was found in coronal view by ABVS.Conclusions ABVS system can obtain effective coronal images of musculoskeletal system lesions,which represents a progress.
